Pin Assignment
3.4.5. Pin Multiplex for Video port
Video port (17 signal) will be GPIO Channel-2 at boot up time. This port can be configured by setting VPSMODE and
VSSMODE bit in Pin Configuration Register (See Chapter 7)
PC Trace Mode is activated by Boot Configuration. Related mode bit is PTSEL, which is in the Chip Configuration Register
(CCFG). Please see Chapter 7 for detail.
Rev. 3.1 November 1, 2005
Note 1: Serial port channel 1 can perform Input and Output.
Note 2: All GPIO port is High-Z mode at boot time.
